"The idea that cognitive and physical function are connected is something that has just come out in the last few years. It is one of the new horizons in health care and prevention," says neurologist and aging expert Dr. Joe Verghese of the Albert Einstein College of Medicine in New York City, who published an article in the New England Journal of Medicine in 2002 showing that changes in walking patterns could be an early sign of dementia.
While further research needs to be done to establish the exact impact of social activity and exercise on specific age-related declines it's likely that a reduction in social activity may simply be a symptom of physical decline, since people may naturally withdraw from social engagement as they lose motor skills most researchers would agree that it is not unreasonable to encourage seniors to get out there more. Only 10% of people over 65 get the recommended amount of exercise (at least 2.5 to 5 hours a week), and given that seniors already tend to be more socially isolated than younger adults, it's difficult to motivate them to become more active. "If you are alone, you are less likely to follow recommendations," notes Verghese. It might help, though, if you visit with Grandma more often and let her know that a regular pastime may just help her stay fitter and sharper longer.
